Wonder Smash

Wonder Smash is a free keyboard-and-sound game for children. Press a letter or number to see it appear with a musical note, or use the on-screen keys on a touchscreen.

How it works

Press a letter or number and it appears in the sky with its own musical note. Move the mouse to trail colour behind it. Click or tap the open scene for a small burst of shapes.

Make it your own

Try Cosmic Candy for stars, Bubble Reef for floating circles, or Electric Garden for petals. The world controls change the visual treatment; the same letter still plays a consistent note.

Try this together

Try your first initial, then someone else’s. Take turns pressing one key and guessing which colour or note comes next. Press Space for a shape surprise.

Controls and useful details

Letters and numbers trigger visual notes. The on-screen keyboard provides the same actions on touchscreens. Escape returns to the home page.

Use the sound and motion controls to suit your family. Young children should play with a grown-up. These are play activities, not assessments or developmental guarantees.
